Why is this man running with cremation ashes?

A Swedish marathon runner and bicyclist, Anders Forselius, has an unusual practice. Starting in 2008, he has carried the cremation ashes of certain deceased strangers on his marathons.

In this way, he allows the deceased persons to vicariously experience adventures their loved ones said they hoped to have in life, such as travelling, running, and climbing mountains. He has run 113 marathons and biked through 33 countries since 1999.
